A months-long manhunt for a Colorado man accused of using his truck as a weapon ended this week through a coordinated effort between federal agents and local law enforcement. The Adams County arrest of David McWilliams follows a violent incident from last year that left a bicyclist with severe injuries and a community searching for answers.
Officials from the Adams County Sheriff’s Office announced Friday that McWilliams, 46, was taken into custody days earlier. The arrest was the culmination of a joint operation with the FBI, targeting a suspect who had been classified as armed and dangerous since he first vanished following the attack.
The capture marks the end of a period of evasion that began in the spring of 2025. For nearly a year, investigators tracked McWilliams, who is now facing a series of grave charges, including first-degree attempted homicide, as the legal system seeks accountability for a crime that police say was intentional.
The May Morning Incident
The case dates back to the early hours of May 10, 2025. According to investigators, the attack occurred just before 6 a.m., a time when roads are typically quiet and visibility is shifting. McWilliams allegedly struck a bicyclist with his truck before fleeing the scene.
The victim, who has not been publicly identified, suffered multiple severe injuries in the crash. A critical detail provided by investigators is that the bicyclist was known to McWilliams, adding a layer of personal betrayal to the violence of the event.
In the immediate aftermath, the Adams County Sheriff’s Office initiated a search for the suspect. As the investigation unfolded, the severity of the injuries and the nature of the collision led authorities to elevate the search to a priority, eventually securing an arrest warrant and warning the public that McWilliams should be approached with extreme caution.
A Collaborative Manhunt
The road to McWilliams’ arrest was not immediate. For months, the suspect remained off the radar of local authorities, prompting the involvement of the FBI to leverage federal resources for fugitive recovery.
The investigation gained significant momentum on August 25, when law enforcement issued a Crimestoppers tip. By engaging the public and offering a pathway for anonymous information, deputies were able to narrow the search parameters. This combination of community intelligence and federal surveillance eventually allowed deputies to pinpoint McWilliams’ location.
The apprehension took place when deputies located McWilliams inside a vehicle. To prevent a high-speed pursuit—which could have endangered other motorists or pedestrians—deputies utilized a Grappler device. The technology, which launches a reinforced net to snag a vehicle’s rear tire and bring it to a controlled stop, proved effective. Following the deployment, McWilliams surrendered immediately and was taken into custody without further incident.
Legal Stakes and Charges
The charges facing McWilliams reflect the gravity of the incident and the intent alleged by the prosecution. In Colorado, first-degree attempted homicide is one of the most serious charges a defendant can face, requiring proof of a specific intent to kill.
Beyond the primary homicide charge, the prosecution has included “sentence enhancers.” These are legal mechanisms that increase the potential penalty based on the specific circumstances of the crime—in this case, the employ of a weapon (the truck) and the resulting serious bodily injury to the victim.
| Charge | Category/Detail |
|---|---|
| First-Degree Attempted Homicide | Primary felony charge |
| First-Degree Assault | Deadly weapon causing serious injury |
| Leaving the Scene | Accident involving serious bodily injury |
| Violent Crime Enhancer | Weapon used in commission of crime |
| Injury Enhancer | Crime caused serious bodily injury |
The use of these enhancers suggests that the District Attorney’s office intends to seek a significant sentence if McWilliams is convicted, reflecting the intentional nature of the strike and the subsequent attempt to evade justice.

McWilliams is scheduled to produce his first court appearance on Friday afternoon. Even as court records have not yet listed his legal representation, the proceedings will determine his initial bond status and the timeline for his preliminary hearings.
